Influences of Clearcut Harvesting and Fertilization on Structure and Function of the Soil Food Web in ICH Forests of Southern Interior British Columbia
This report details two studies investigating the impacts of common forestry practices on soil health in Interior Cedar-Hemlock forests.

The first study compared clearcut harvested areas to adjacent forests, finding that clearcutting generally reduced key indicators of soil food web activity and nitrogen cycling. The second study examined the effects of broadcast fertilization on clearcuts, revealing it boosted nitrogen availability but also increased the potential for nitrogen loss through leaching and denitrification. This research aims to inform foresters and managers about how harvesting and fertilization influence soil ecosystems, suggesting ways to mitigate negative impacts and sustain forest productivity. -
Comparing Clearcutting and Alternatives in a High-Elevation Forest Early Results from Sicamous Creek
This extension note reports on the early findings of the Sicamous Creek Silvicultural Systems project, a long-term study comparing different forestry practices in high-elevation forests of British Columbia. The central theme is the evaluation of clea...This extension note reports on the early findings of the Sicamous Creek Silvicultural Systems project, a long-term study comparing different forestry practices in high-elevation forests of British Columbia. The central theme is the evaluation of clearcutting versus alternative harvesting methods, such as small patch cuts and individual tree selection, regarding their impacts on various ecological and economic factors. The purpose of this note is to summarize initial results concerning harvest costs, regeneration, soil conditions, microclimate, and biodiversity, ultimately aiming to inform more ecologically diverse and sustainable forest management in these sensitive ecosystems. -
Can Thinning and Fertilizing Young Lodgepole Pine Mitigate Future Timber Supply Challenges
This extension note reports on a 14-year study investigating how thinning young lodgepole pine stands to different densities and repeatedly fertilizing them with multiple nutrients affects their growth. The central question explored is whether these ...This extension note reports on a 14-year study investigating how thinning young lodgepole pine stands to different densities and repeatedly fertilizing them with multiple nutrients affects their growth. The central question explored is whether these silvicultural practices can accelerate stand development enough to help offset future timber supply shortages anticipated due to the mountain pine beetle epidemic. The research measured the impact of these treatments on tree size and overall stand volume, aiming to determine optimal strategies for mitigating timber supply challenges in the interior of British Columbia.
